PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 426,774, dated April29, 1890.

' Application filed February 11, 1890. $erial No. 339,968. (No model.)

To all whom it may concern:

Be it known that I, EDWARD E. CLAUSSEN, of the city and county ofHartford, State of Connecticut, have invented a new and useful PaperBag, of which the following is a true and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

My invention relates to the manufacture of paper bags; and it consistsof a new form of bag collapsed into convenient form for shipment andreadily expandible into a rectangular box-like form.

The nature of my invention will best be un- I 5 derstood by anexplanation of the various foldin gs by which a paper blank can beformedinto my improved bag, and in the drawingsI have illustrated eachmanipulation of the blank as well as the completed bag.

In the drawings,.Figure l is a plan view of a blank suitable for use inthe manufacture of my improved bag and having indicated on it thevarious lines of fold formed in the process of making the bag. Fig. 2 isan end view of the blank, showing certain of the creases preferablyformed in it. Figs. 3, 3%, 4, 5, 6, 7, 8, 9, and 10 illustrateconsecutive folds made in the blank in the process of making the bag.Fig. 11 shows the completed bag; Fig.

0 12, the completed bag opened up. Fig. 13 is a view of a blank adaptedfor use in making one modification of my improved bag. Figs. 14 and 15illustrate the novel folding to which this blank is subjected in formingit into a bag. Fig. 16 shows the completed bag made from theblank ofFig. 13, and Fig. 17 shows the same bag opened up. Fig. 18 illustratesanother method of folding the blank of Fig. 13 in the completion of thebag. Fig. 19 shows the bag made by this latter folding, and Fig. 20 thesame bag opened up. Fig. 21 shows still another form of blank adaptedfor the manufacture of another modification of my improved bag. Figs. 22and 23 illustrate the 4 5 mode in which this blank is folded in thecompletion of the bag made from it. Fig. 24

shows the completed bag, and Fig. 25 the same bag opened up.

Fig. 1 shows a paper blank A, adapted for the manufacture of my improvedbag, the paper being preferably creased, as indicated at 1, 2, 3, 4, and5. B is a rectangular plate of the breadth of the desired bag, which islaid on the center of the blank with its front edge tom in the bag, asdo also the corresponding points Z l on line 1 and the portions of thelines 1 to 5 which lie outside of the bottomdefining lines. o l e Z formfolds in the bellows-folded sides of the bag, while those portions lyingbetween said lines form folds of the bellows-folded bottom.

The first fold in the manipulation of the bag is best made as shown inFig. 3%, Sheet 2, the lines at cl being folded down along the edges 1)of the plate B, and the paper creased on the oblique lines 6 e, asshown, so as to form the two outwardly-extending flaps with the rest ofthe paper erected thereon at right angles and in a box-like form. Theoutwardly-extending flaps may then be folded in upon the lines (1 d, asshown in Fig. 3, and paste being applied so as to hold the lapping edgestogether the back of the bag is formed. Preferably, however, thisfolding is not made until the sides and bottom of the bag are formed;but I have shown it as completed in the drawings to save space andbecause it is really immaterial at what time the edges are overlapped.The next folding is shown in plan in Fig. 4 and in perspective in Fig.5. In making this folding flat plates G and H H are convenientinstrumentalities. The upwardlyextending parts of the blank are foldeddown on the lines 5 and d d, and at the same time folded upon the lines4 andit'. The portion of lines 1' between t" andc' extends out at rightangles to the rest of the fold, as shown, and an oblique fold is formedbetween the points 1" and c. The next fold is made by pushing out anddown the paper above the lines it and 4, and at the same time turning itup upon the lines j j and 3, as is shown in Fig. 6. This folding alsoforms the oblique folds tj' and completes one of the two bellows foldsin the sides and bottom of the bag, and it will be noticed that a trianldown, as shown in Fig. 16, the resultant bag gular section of thebellows-folded plies of the sides bounded by the lines 0 17 7" is turnedup between the plies and folded over the bellows fold of the bottomalong the line 27 11 This is a characteristic fold of mybag. The nextfolding is made by pushing or folding the paper in and down about linesj and 3, and at the same time folding it up about lines Z; Z: and 2, asshown in Fig. 7, folds Z770 being formed like 7." i and also an obliquefold j 70, like fold e Z. The paper is then folded down and out aboutlines 70 Zn and 2 and up about lines Z Z and 1, forming oblique folds kZ, being formed as were folds Z 7". (See Fig. 8.) Next the upturned plyof the paper is folded down flat on the lines I and m an, as shown inFig. 9. The outwardly-extending flaps are then folded in upon the linesZ Z and pasted together, where they everlap. (See Figs. and 11.) Fig. 12shows the completed bag opened out to a rectangular box-like form.

Figs. 13 to show a modified form of blank and the way in which it may befolded into my bag. Slits 1) p o o are made in blank A to points 19 pand 0 0, said points being, respectively, in continuation of the oblique lines 1." 0 and 71' Z. (See Fig. 13.) The folds made in this blankare identical with those already described, with the exception of thelaps to form the front and back. As to these, the blank having beenfolded to the state shown in Fig. let, the two upwardly-extending sidelaps maybe folded in and down on lines Z Z, and the lap extending aboveline ,1 folded out and down, as shown in Fig. 15. Oblique folds are thusformed on the lines Z 0 Z 0. The side laps having been pasted together,the flap bounded by the lines 1. Z Z 0 o o o is turned over on line 1and pasted opened out being shown in Fig. 17. Instead of thus foldingthe paper it may be folded from the form shown in Fig. 14: in the wayshown in Fig. 18, the flap bounded bylines 1 Z 0 0 Z 0 0 being firstfolded in and the side laps folded upon it on the lines Z Z and w r. Theresultant bag partially opened is shown in Fig. 19 and fully opened inFig. 20. r

In Figs. 21 to 25 I have illustrated another modification of my bag. Theblank A (see Fig. 21) is slit at'Z Z and 0' 1' to points lying in thelines c e and m m. Slits a a s s are made in the edges of the blank inthe lines e Z e Z, shown, and the paper cut away between said slits, asat t a and 0" s'.- The blank having been folded as before to the formshown in Fig. 22 is then finished by pushing in and down the edges ofthe paper upon the lines Z Z and 1, oblique folds Z '1' being formed indoing so. The sides are pasted together, and a line of paste on the edges s fastens it to the sides, as shown. (See Figs. and 24.) The completebag'opened out is shown in Fig. 25.

llavin g now described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The described paper bag having its sides and bottom folded into doublebellows folds, a triangular section of paper at the bottom of eachbellows fold in the sides being turned up in the fold so as to overliethe ends of the corresponding bellows fold of the bottom, and its frontand back being formed by folding down and pasting together the ends ofthe blank.
